6 Crazy Facts About Space That Will Make You Feel Tiny

A Star That Could Swallow Five Billion Suns

The biggest known star in the universe is UY Scuti, a hypergiant star so massive that it can fit the volume of almost five billion suns inside it. It’s roughly 9,500 light-years away, which is probably a good thing. If you replaced our Sun with UY Scuti, its surface would extend past the orbit of Jupiter. The Earth wouldn’t just be scorched — it would be swallowed whole without even noticing.
